  • Small Wind Electric Systems

    2021 8 8 The diameter of the rotor defines its swept area or the quantity of wind intercepted by the turbine The tail keeps the turbine facing into the wind Towers Because wind speeds increase with height a small wind turbine is mounted on a tower In general the higher the tower the more power the wind system can produce.

  • How much wind turbine power can I create

    2021 10 27 The power output from a wind turbine at any moment is determined by the speed of the wind at that moment though there will be a maximum power output based on the wind turbine generator rating which is closely related to the swept area of the blades For example a wind turbine with a rotor diameter of 52 metres would normally have a maximum
